Panasonic RP-HJE900 Zirconia Headphones

Panasonic's RP-HJE900 is the first pair of headphones on the market to use Zirconia, a material many times stronger than conventionally used aluminum or plastic. It also makes for less resonance than those materials and creates better, audiophile-grade sound reproduction. The headphones feature 12.5mm drivers and have a frequency response of 6Hz to 26Hz covering an incredibly wide range of sound. And because Zirconia is a material that could very well last a lifetime, the wires are removable and can be replaced if they ever fray. Available May. Link: $230
